SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 485,811, dated November 8, 1892.

Application led July 15, 1892. Serial No. 440,088. (No model.)

To all whom, t may concern;

Be it known that l, JOHN N. FARNHAM, of Waltham, county of Middlesex, State of Massachusetts, have invented an Improvementin Blind-Fastenings, of which the following description, in connection with the accompanying drawings,is a speciicatiomlike letters and figures on the drawings representing like parts.

This invention has for its obj ect to construct a blind-fastening whereby the blinds may be opened and closed from within and held securely locked bot-h opened and closed and also in one or more intermediate positions.

In accordance with this invention the blinds are hung on pivots in the usualmanner, and to the middle of the lower end of each blind or thereabout one end of a flat spring-acting bar is connected, the opposite end of said fiat bar having a series of holes, and four projections rise from the window-sill at desired points, with which said bar co-operates, two of which enter the holes in said bar and hold the blind wide open, another of which enters one or another hole in said bar and holds the blind in an intermediate position, while two of which are so located as to receive between them the bar and hold the blind closed. The free end of the iat spring-acting bar is upturned to serve as a haudpiece or means by which it may be grasped by hand, so as to serve as a lever to swing the blinds.

Figure l shows in horizontal section a window-casing and two blinds and blind-fastenings therefor embodying this invention, one blind being closed and locked and the other being opened and locked; Fig. 2, a front view of the lower end of one of the blinds, showing the blind-fastening in edge View; and Fig. 3, a similar view to Fig. 1, showing the blind locked in an intermediate position.

The sides a l) and sill c of the window-casing, and the blinds d e, hung on pivots d e', are or may be of any usual or suitable construction. A flat spring-acting bar of steel or other suitable material fis bent or curved at right angles, or substantially so, inahorizontal plane at one end, as at f', and is connected 5o at said end in a loose or pivotal manner, as

by a screw 2, to the middle of the lower end of the blinds. The opposite end of the flat bar f is slightly npturned, as by an offset at f2, to present a handpiece which may .be grasped by hand for the purpose of movlng the bar. Along the bar f near the upturned end aseries of perforations 3 are provided, arranged at desired distances apart. Pins 4. 5 6 are driven into the sill c at different points, as shown, which enter the perforations of the flat bar f to thereby hold said bar rigidly 1n its different positions. Two of the pins, as 6, are arranged in line with each other and parallel with the outer face of the side a, or b, and when the blind is swung wide open said pins enter two of the perforations of the bar, and said bar is made of sufficient width to at such time bear against the outer face of the side o or b, so that the side a or b serves as an additional means of holding the bar f. Thus when the blind is wide open or swung back against the side wall of the building it is locked by the barf, being held by the pins 5 6 and by the outer face of the side b, as shown in Fig. l. When the blind is closed, as also shown in Fig. l, the iiat bar f is brought into parallelism with the blind and between the pin 4 on one side and the staple, pin, or projection '7 on the other side, so that it is securely held. The fiat bar f by its spring action bears firmly upon the top of the Asill c, thereby holding itself upon the pins, or between the pins, as the case may be, without the employment of additional lookin g devices to hold it down. When the blind is swung part way open, as shown in Fig. 3, the pin 4 enters one of the perforations 3 in the fiat bar, thereby holding it.

Itis obvious that pins may be located at other desirable points, which may enter perforations in the bar, and thereby rigidly hold the blind in any intermediate position.

If it is desired to use this form of blindfastening in connection with blinds hung in a different manner from that herein shown, the said flat bar f will be bent to accommodate itself to the shape of the window-casing, so that I do not desire to limit my invention to any particular shape of the bar f so long as it is made fiat and spring acting to thereby hold itself on fixed pins provided for the purpose without the aid of addition al locking IOO open, the projection 4, entering one or another` perforation and holding the blind in an inx5 termedate position, and the projections 4 7, bearing against the sides of the bar and holding the blind closed.

In testimony whereof I have signed my name to this specification in the presence of 2o two subscribing witnesses.
